The problem is her concern seems to be rather selective. Wanting justice for all in the face of Hamas atrocities is weak to say the least. The YT clip posted by
@dutchguylivingintheuk was ironic to say the least.
The actions of anyone that knowingly will long term lead to the harm of others would indeed be evil. Greta would not have been wrong imo to use that expression.
It took some guts to get up in front of the UN to give her speech at her age. On the other hand 'you have stolen my dreams and childhood' seems to make the issue revolve around her. She had to add 'I am one of the lucky ones' to deflect to my mind the legitimate criticism from someone in the developing world that living in Sweden she is not so much lucky as privileged. It's true that she wasn't forced to make the speech but to have been filled with so much fear seems to me to be bordering on child abuse. That was my reaction at the time.
Some brief footage of her at Glasgow showed the adulation has gone to her head. Probably not that surprising.
From the point of view of climate alarmism she was a propaganda coup, and wrong-footed many a sceptic. This was shown in their failure to deal with her, frequent ad hominum attacks, and on the comment sections of some sceptic sites appallingly viscious nasty comments. I found tbh some of it disgusting. They should have left her alone, seen she was a propaganda ploy, and dealt with the issues, but you are right she did touch a raw nerve.
I do think it is of concern that she is gaining power and influence without responsibility. It's easy to say don't carry on with business as usual, but how do you actually do that without wrecking the world economy.
